Area \ of \ top \ triangle =  \frac{1}{2} \times base \times height
       \boxed{\frac{1}{2} \times 7 \times 2 = 7 cm^{2} }

Area \ of \ the \ rectangle  = length \times width
      \boxed {7 \times 4 = 28 cm^2}

Area \ of \ bottom \ triangle = \frac{1}{2} \times base \times height
      \boxed {\frac{1}{2} \times 7 \times 2 = 7 cm^{2}}

\boxed{\boxed{Total \ area = 7 + 28 + 7 = 42 cm^2}}

Whats the cost of each vegetable if 5 squash and 2 zucchini is $1.32​
alex41 [277]

Answer:

Step-by-step explanation:

 

We first need to define a couple of variables.  Let s = the cost of 1 squash and z = the cost of 1 zucchini.

 

Now lets translate the words into algebra:

 

"The cost of 5 squash and 2 zucchini is $1.32"  ===>  5s  +  2z  =  1.32

 

"Three squash and 1 zucchini cost $0.75"  ===>   3s  +  z  =  0.75

 

There are several ways to solve systems of equations.  Let's use substitution.  We can find what z equals in terms of s by manipulating the second equation:

 

 3s  +   z   =   0.75

-3s                 -3s

------------     -------------

           z    =  -3s  +0.75

 

Now lets substitute (-3s + 0.75) into the first equation for z, then solve for s:

 

 5s + 2(-3s + 0.75) = 1.32

 

Can you handle it from here?

 

(Hint: Once you have solved for s, you can substitute that value back into either of the equations and solve for z.)

1. Suzette ran and biked for a total of 44.75 mi in 4 h. Her average running speed was 6.5 mph and
Andru [333]

Suzette ran for 1.6 hours and biked for 2.4 hours.

Let x = total hours Suzette ran.

Let y = total hours Suzette biked.

The equation to solve the question will be:

x + y = 4 ...... i

6.5x + 14y = 44.75 ....... ii

From i, y = 4 - x

Put the value of y into equation ii

6.5x + 14y = 44.75

6.5x + 14(4 - x) = 44.75

6.5x + 56 - 14x = 44.75

Collect like terms

6.5x - 14x = 44.75 - 56

-7.5x = -11.25

x = 11.25/7.5

x = 1.6 hours

Since x + y = 4

1.6 + y = 4

y = 4 - 1.6

y = 2.4 hours.

Suzette ran for 1.6 hours and biked for 2.4 hours.

Write the standard form of the equation of the circle below.
sergeinik [125]

Answer:

x^2+(y+1)^2=2

Step-by-step explanation:

We use the formula for a circle with center at (0, -1), that goes through the (x, y) point (-1, -2):

(x-0)^2 + (y-(-1))^2 = R^2\\Using \,\,\,point\,\,\,(-1, -2)\\(-1-0)^2+ (-2+1)^2 = 1 + 1 = 2 = R^2

Therefore, the equation of this circle can be written as:

x^2+(y+1)^2=2
